RF coaxial connector flange explanation


Xiaotian found that most of the RF coaxial connectors have XX waterproof flanges. What is the flange? The following Xiaotian will give you a detailed introduction. "Flange" is a transliteration of Flange, also known as a flange or flange, originally referred to as a convex edge on a structural or mechanical part that is perpendicular to the axis of the component. Many people often call it a flange. According to the standard name, it is a "flange" and the word "disk" can be removed.

A flange is a component that connects a pipe to a pipe, a valve fitting, or the like. Flange-to-thread connection (wire-to-wire) flanges and welded flanges and ferrule flanges are key connections for pipe construction.

Flange connection refers to the detachable and sealed structure of the sealing structure consisting of flange, gasket and bolt. It is called flange joint. In the pipeline installation project, it is called flange connection.

Flange connection is to fix two sections of pipe, pipe fittings or pipe fittings to one flange separately. The gasket is placed between the sealing faces of the two flanges. The flange has bolt holes (not the same pressure). The diameter of the bolt hole and the number of bolts are different.) Insert the bolt into the bolt hole of the flange. After tightening the nut, the specific pressure on the surface of the gasket exceeds a certain amount and then deform and fill the seal. The microscopic unevenness on the surface makes the two flange connections tight and not leaking. Some equipment or pipe fittings have their own flanges, which are called integral flanges, and flanges are also required for piping.

Flange connection is a detachable connection that is easy to use and can withstand high pressures. In industrial piping, flanged applications are very common.

There are four basic types of flange sealing surfaces: flat sealing surface flange (including plane, code FF and protruding surface, code RF), suitable for places with low pressure and medium non-toxicity and nominal pressure lower than 4.OMPa Grade; convex and concave sealing surface flange (code FM), can be used in places with relatively low pressure, can be used in nominal pressure 2.5, 4.0, 6.4MPa grade; groove sealing surface flange (code TG), can be used for flammability , explosive, toxic medium and pressureful occasions; ring joint surface flange (code RJ), mainly used in high temperature, high pressure two high working conditions.

Flanges are classified according to materials, such as cast iron flanges (used as integral flanges), carbon steel flanges, stainless steel flanges, alloy steel flanges, copper flanges, etc.

The flange can be divided into a pipe flange and a pressure vessel flange according to the connected components.

The flange is connected to the pipe by means of a threaded connection flange (threaded flange) and welded flange. Only the low-pressure small-diameter threaded flange (theoretically DN15~DN150, the actual use category is smaller), the big boy uses the welding flange, the thickness of the flange with different pressure and the diameter of the flange, the bolt hole diameter The number of bolts is different.

Common flanges are flat weld flanges and butt weld flanges. The flat welding flange has a weak rigidity and is suitable for a pressure P<4.0 MPa; the butt welding flange is also called a neck or a high neck flange, and has a large rigidity, and is suitable for a high pressure temperature occasion.
